Description
Technical field
This utility model relates to a kind of sedimentation tank, particularly relates to a kind of wetland purification from sedimentation tank.
Background technology
Sedimentation tank is that application precipitation removes a kind of structures of float in water.Sedimentation tank is the most widely
Use.Its pattern is a lot, can be divided into flat flow, vertical-flow and radial-flow three kinds by pool inner water flow path direction.
In recent years, Sewage Plant takes up an area to control more and more sternly, how to ensure sedimentation tank effect and sludge reflux concentration, to sewage
The more stable operation up to standard of factory is most important, if designing unreasonable, being just difficult to reach present water outlet and requiring and energy saving requirement.According to
From the point of view of some Large Sewage Treatment Plants take Radial Flow Secondary Sedimentation Tank at present, taking up an area bigger, management operating is more complicated, especially during maintenance more
It is difficult to switch, for ensureing that each pool water level height is identical, the highest to construction and foundation requirement, and the instability of sludge discharging period also leads
Cause the shock resistance of each pond poor.
Although both at home and abroad much water treatment research mechanism has carried out numerous studies to second pond, develop some novel two
Heavy pond, it is paid attention to the lifting to efficiency, but is still difficult to solve occupation of land problem.But along with sewage disposal planning large-scale
Changing, process the intensive of occupation of land, process the automatization of technique, tradition second pond group number gets more and more, and floor space is increasing,
Invest more and more higher, due to factors such as settlement of foundation, it is impossible to ensure that often group treating capacity is impartial and weir load is consistent, treatment effect
It cannot be guaranteed that.In a lot of cities, soil has become as the bottleneck of various facility development, a lot of equipment and technology because of floor space
Excessive and cannot be carried out.
Utility model content
The purpose of this utility model be big for existing municipal sewage treatment sedimentation tank floor space, invest high problem,
Propose a kind of take up an area compact, energy consumption is low, conveniently adapt to water yield change, anti-shock loading is strong, go out the little wetland purification of difficulty of becoming silted up from
Sedimentation tank.
For achieving the above object, this utility model provides a kind of wetland purification from sedimentation tank, including four surface concretes
Pool wall and a concrete bottom, two opposites of described concrete-pool-wall are respectively equipped with water inlet and outlet, described from
Sedimentation tank is internally provided with at least two-layer barricade, identical from the degree of depth of sedimentation tank described in the height of described barricade, adjacent gear
The top of wall is staggeredly equipped with permeable mouth, and described permeable mouth is provided with barrier drainage screen, and described concrete-pool-wall, barricade,
The serpentine flow circulation passage of permeable interruption-forming sewage.
Preferably, described from the width of sedimentation tank be 50～100m, described from the degree of depth of sedimentation tank be 7～8m.
Preferably, the width of described permeable mouth is 30～50cm, and the height of permeable mouth is 50～100cm.
Preferably, it is provided with toe between described concrete-pool-wall and described concrete bottom.
Preferably, described barricade is provided with planting groove, plants and be implanted with plant in described planting groove.
Preferably, the width of described barricade is 20～40cm.
Based on technique scheme, the utility model has the advantages that:
Wetland purification of the present utility model is from sedimentation tank, by being arranged on the barricade within sedimentation tank, make current along
Barricade flows, and by serpentine flow circulation passage, increases flow time and the length of current, and the self-purification function of current is strengthened.?
Barrier drainage screen is installed in barricade one end, keeps off scum silica frost in water body in outside, and permeable mouth is arranged on gear coping, makes precipitate stay
Outside barricade；High-front shovel passing road can be set between sedimentation tank, it is simple to cleaning sedimentation tank, arrange bottom sedimentation tank
There is toe, reduce the resistance of current, make current flowing unimpeded.
Entering interior to arrange a plurality of waterwall from sedimentation tank, extending the flow distance of current, it is simple to deposit in water body
Sinking, arrange barrier drainage screen at barricade top, will enter next stage precipitation after contaminant filter in current, multiple sedimentation tanks are arranged side by side
Middle barricade can pass through high-front shovel, facilitates the cleaning of sedimentation tank, and integral arrangement has saved construction investment and place, joint
Save later maintenance expense, had that occupation of land is compact, energy consumption is low, adapt to water yield change, anti-shock loading is strong, go out the spy that difficulty of becoming silted up is little
Point.

Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
This utility model provides a kind of wetland purification from sedimentation tank, as shown in FIG. 1 to 3, illustrated therein is this reality
By novel a kind of preferred implementation.Described wetland purification includes four sides concrete-pool-wall 2 and a coagulation from sedimentation tank
Soil bottom surface 5, two opposites of described concrete-pool-wall 2 are respectively equipped with water inlet 7 and outlet 8, described in sedimentation tank
Portion is provided with at least two-layer barricade 1, identical from the degree of depth of sedimentation tank described in the height of described barricade 1, the top of adjacent barricade 1
Being staggeredly equipped with permeable mouth 4, described permeable mouth 4 is provided with barrier drainage screen 3, and described concrete-pool-wall 2, barricade 1, permeable
Mouth 4 forms the serpentine flow circulation passage of sewage.
Specifically, of the present utility model from sedimentation tank main body be uncovered rectangle form pool structure, including four sides concrete-pool-wall 2
With a concrete bottom 5, two opposites of described concrete-pool-wall 2 are respectively equipped with water inlet 7 and outlet 8.Preferably,
Described is 50～100m from the width of sedimentation tank, and described is 7～8m from the degree of depth of sedimentation tank, and sewage introduces from channel or straight
After connecing inflow, area increases 5～10 times, and filter area doubles.The described degree of depth from sedimentation tank is set to 7～8m, protects
Demonstrate,prove bigger long-pending silting-up, be also convenient for the desilting work of excavator in maintenance process simultaneously.
As shown in Figures 2 and 3, described it is internally provided with at least two-layer barricade 1, the height of described barricade 1 from sedimentation tank
Described identical from the degree of depth of sedimentation tank, the most described barricade 1 has cut off the bottom from sedimentation tank completely, prevents mud mutual
Flowing, affects water quality.As it is shown in figure 1, the top of adjacent barricade 1 is staggeredly equipped with permeable mouth 4, permeable mouth 4 is arranged on barricade 1
Top so that mud the most slowly settles, upper strata more clear water stream then enters next stage gear from permeable mouth 4
